Stigma

Flowering plants: The stigma is the part of the pistil which receives pollen

Medicine - a stigma is a non-specific sign or mark which indicates to an observer that a person is ill (weight loss or pallor, for example). Unlike sequelae, a stigma disappears in principle after the person has recovered. In contrast to a symptom, it does not provide reliable information about the type of disease.

Biology - a stigma is a small opening through which air enters the body. Stigmata are located on the sides of the body of an insect.
